ABSTRACT
Objective To investigate the prognostic value of fever burden in traumatic brain injury (TBI) patients.Methods A retrospective analysis of 355 TBI patients admitted to the emergency department and intensive care unit from November 2010 to October 2012 was performed,and the Glasgow outcome scale (GOS) was followed-up 6 months after the injury.The patients were divided into two groups according to the GOS:good outcome group (4 to 5) and poor outcome group (1 to 3).Relevant clinical findings were studied by statistical description,logistic regression analysis,Spearman correlation analysis and ROC curve analysis.Results Fever burden level was continuously increased with the decrease of GOS from score 5 to 2,except for score 1 of GOS,which was corresponding to a significant lower fever burden.There were significant differences in age,pupil reactivity,Glasgow coma scale (GCS) and fever burden between two groups (P ＜ 0.05).Compared to the good outcome group,the poor outcome group was featured with more advanced average age (P =0.000),poorer pupil reactivity (P =0.000),lower GCS score (P =0.000) and higher fever burden level (P =0.000).Univariate logistic regression analysis suggested that age,GCS,pupil reactivity and fever burden level (OR 1.166,95％ CI:1.117-1.217) were associatedwith poor outcome.The fever burden level and the other independent prognostic predictors as age,GCS and pupil reactivity were further included in the multivariate logistic regression model,and the adjusted OR of fever burden level was 1.098 (95％ CI:1.031-1.169,P =0.003).ROC curve analysis showed the respective AUC for fever burden was 0.713 (95％ CI:0.663-0.760).The relevant analysis revealed a significant negative correlation between the fever burden and the GOS score (r =-0.376,95％ CI:-0.462--0.283,P =0.000).Conclusions Fever burden can be considered as an independent predictor of poor outcome of patients with TBI.The TBI patients with early onset of high levels of fever burden will have increased poor outcome risk.
ABSTRACT
Objective To explore the effects of high-dose ambroxol hydrochloride (Mucosolvan) on pulmonary protection and anti-inflammatory in traumatic brain injury patients treated by mild hypothermia.Methods From June 2008 to June 2012,40 elderly traumatic brain injury patients aged 60-70 years treated by mild hypothermia in our hospital were selected.Patients were randomly divided into two groups:low-dose ambroxol hydrochloride group and high dose ambroxol hydrochloride (n=20,each).Patients in low-dose ambroxol hydrochloride group were treated with ambroxol 30 mg plus saline infusion,3 times/day; while patients in high-dose ambroxol hydrochloride group were treated with ambroxol 300mg plus saline infusion,3 times/day; both groups were treated for 7 days.The changes of characteristic and quantity of sputum,PaO2and PaO2/FiO2,and serum TNF α level were analyzed at day 1,3,7.Duration of mechanical ventilation,tracheotomy proportion,and mortality were compared between the two groups 3 months after treatment.Results At day 3-7 after the intervention,the sputum got thinner and less,and more easy to suck in highdose group than in low-dose group (thin sputum proportion:75％ vs.40％,P =0.025; clean proportion by once suction:65％ vs.25％,P=0.011).The improvement of PaO2,PaO2/FiO2 were more significant in high dose group than in low dose group (PaO2 ∶ 3d,(92.3±12.3) mm Hg vs.(83.3±15.2) mm Hg,P=0.046;7d,(95.9±12.5) mm Hgvs.(87.1±11.7) mm Hg,P=0.028;PaO2/FiO2∶3d,(290.8± 15.8) mmHgvs.(221.8± 16.4) mm Hg,P=0.000;7d,(296.3±16.9)mm Hg vs.(238.4±15.0) mm Hg,P=0.000).Serum concentrations of TNF α was lower in highdose group than in low dose group [3d,(54.1± 4.9) ng/L vs.(71.4± 5.6) ng/L,P=0.000;7d,(35.1± 2.7) ng/L vs.(63.3±4.3) ng/L,P 0.000].Duration of mechanical ventilation was shorter and tracheotomy proportion was lower in high dose group than in low dose group [(116.8±18.7) hrsvs.(178.4±35.5) hrs,P=0.000; 25％ vs.60％,P=0.025].There was no significant difference in mortality between groups 3 months after treatment.Conclusions The application of high dose ambroxol can improve respiratory function,decrease duration of mechanical ventilation and tracheostomy proportion,and reduce the systemic inflammatory response in elderly traumatic brain injury patients treated by mild hypothermia,but without long-term survival benefit.
ABSTRACT
Objective To study the clinical significance of the injury and functional change of hypothalamic-pituitary-adrenal (HPA) axis after acute severe traumatic brain injury (TBI) in the rats.Methods A total of 60 adult healthy male Spraque-Dawley rats were randomly (random number) divided into 3 groups (n =20 in each group):sham operation group,model group and treatment group.The TBI models of rats were established by Feeney' s method.A low dose of dexamethasone (0.6 mg/kg) was injected into the abdominal cavity 20 minutes,24 hours and 48 hours after injury in treatment group,while rats of sham operation group and model group received equal volume of normal saline instead.All the rats were injected 1 μg adrenocorticotropic hormone (ACTH) into the abdominal cavity.The related parameters were detected at four time points,3 hours,12 hours,24 hours and 72 hours after cerebral contusion.The plasma corticosterone (CORT) and ACTH levels were measured by chemiluminescence.The hypothalamic,pituitary and adrenal of the rats were taken out for observing interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) expression detecting by immunohistochemical techniques at 72nd hour after TBI.One-way ANOVA and SNK-q test were used to analyze the results with SPSS 17.0 software package.Results The levels of ACTH and CORT on 3rd hour of model group raised remarkably compared with that of sham operation group,then they reduced gradually.The levels of CORT were lower than that of sham operation group at every time points after ACTH stimulation test (P ＜0.05 or P ＜0.01).The levels of CORT at all time points of treatment group were changed remarkably compared with that of model group.However,the ACTH levels of treatment group on 24 h increased slightly than that of model group.And the tendency of them was similar to model group (P ＜ 0.05 or P ＜ 0.01).The number of the hypothalamus and pituitary cells which express IL-6 and TNF-α in model group was more significantly increased when compared with that in sham operation group (P ＜ 0.01),while the number of this kind of cell in treatment group was significantly decreased than that in model group (P ＜ 0.01).The number of the adrenal cortex cells which express IL-6 in treatment group was more significantly decreased when compared with that in model group (P＜ 0.01),while the number of this kind of cell in model group was significantly increased than that in sham operation group (P ＜ 0.01).However,there was no significant difference of the TNF-α between all the groups (P ＞ 0.05).Conclusions Functional change of adrenal occurs early in the severe acute traumatic brain injury rats,and the response of adrenal to ACTH decreased as time goes by.Low-dose,short-course dexamethasone can delay the pathological changes,reduce the inflammatory response of HPA axis and increase the sensitivity of adrenal response to ACTH.
